Description
The PI3A3160 is a fast Dual single-pole double-throw (SPDT)
CMOS switch. It can be used as an analog switch or as a low-
delay bus switch. Specified over a wide operating power supply
voltage range, +1.5V to +3.6V, the switch has an On-Resistance
of 0.4Ω at 3.0V.
Control inputs, IN, tolerates input drive signals up to 3.3V, inde-
pendent of supply voltage.
PI3A3160 is a lower voltage and On-Resistance replacement for
the PI5A3158.
